SPECIFICATION forming part of Letters Patent lfl'o. 732,309, dated. June30, 1903.

Application filed April 6, 1903. Serial No- 1 7' 11105913 T0 or whom itmay concern.-

Be it known that I, J OHN WINSESLAUS MAR- SHALL, a citizen of the UnitedStates, residing at Butte, in the county of Silverbow and State ofMontana, have invented certain new and useful Improvements in Clamps;and I do hereby declare the following to be afull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying, drawings, and to the figures of reference markedthereon, which form a part of this specification.

This invention relates particularly to clamps adapted to attach patchesto bursted hose; but it is not limited thereto and may be applied togreat advantage inthe attachment of any kind of pipe-coverings to repairleaks, to

press veneer to round columns, posts, or balusters, to couple pipes, andfor various other uses unnecessary to specify.

It has for its object to produce an improved clamp adapted for use uponpipe of any size and is so constructed that the clamping strap or covermay be readily detached or attached. This is advantageous in workingaround pipes in corners or near walls, in which case the main parts ofthe clamp can be detached from the strap or covering and the latterinserted through a narrow space before the clamp is attached. Theconstruction permits the attachment of any kind of material-such asflexible metal, cloth, or leather-as a strap or covering.

In the accompanying drawings, Figures 1, 2, and 3 are respectively end,side, and top views of the device.

Referring specifically to the drawings, 6 and 7 indicate a pair of clampmembers, preferably formed of metal and bent at substantially a rightangle, producing flanges 6 and 7 which are faced and adapted to bedrawnv together by a thumb-screw 8, extending therethrough. This screwis threaded into only one of the flanges and extends loosely through theother, so that the parts may take the necessary inclination consequenton use with pipes.of different sizes. The other flanges or parts of themembers (indicated at 6 and 7 extend outwardly in opposite directions.

At 9 is indicated the band or strap, which as referred to above may bemade of thin flexible metal or flexible fabric of any kind. The ends ofthis band are clamped by means of screws 10 between the parts 6 and 7and removable plates, (indicated at 11.)- The screws 10 serve to attachthe plates to the under side of said parts and also to clamp the ends ofthe band therebetween'. The inner edges of the plates 11 are beveled toa thin edge, as indicated at 11, over which the ends of the band arebent. The outer edges of the plate are turned up, as at 11 to-bearagainst the outer ends of the 'members 6 and 7 so that they will notturn on the screws 10. At 12 is indicated a rubbercovering or packingwithin the band, particularly useful when hose or water-pipe is patched.

In the use of this device the band being readily separated from theclampmembers can be made of any length desired and by attachment of theclamp thereto can then be tightened around the pipe. In use in cornersor close to walls the band is first slipped around the pipe, and thenits ends are clamped under the plates 11', as explained above, afterwhich by means of the thumb-screw 8 the members are brought together andthe band tightened. In this respect the device is superior to those inwhich the ends of the band are riveted or otherwise firmly fixed to theclamp members and with which accordingly bands of different lengthscannot be easily substituted. v

My invention may be used whenever it is desired to draw the ends of aband or strap together around an object of any size.

What I claim as new, and desire to secure by Letters Patent, is-

The combination with a band, of angular clamp members having facedflanges and a screw extending between the flanges,.a de tachable plateunder each member, and a band the ends of which are bent over the inneredge of the plates and clamped between the plates and said members.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN WINSESLAUS MARSHALL.
